Benefits of technology

The present disclosure is about methods and apparatuses for assembling absorbent articles. Specifically, it is about how to sever elastic strands in a continuous elastic laminate during the assembly process. The patent text describes a cutting apparatus with a cutting roll and an anvil roll, which can intermittently deactivate or seve the elastic strands in the laminate as it advances through the machine direction. The technical effect of this patent is to improve the assembly process of absorbent articles by automating the severing of elastic strands in a continuous elastic laminate.

Problems solved by technology

However, some current configurations have certain drawbacks.
For example, some present cutting apparatuses may cause unintended damage to the elastic laminate, such as by severing the substrate while cutting the elastic.
In addition, the blades on some current cutting apparatuses may be susceptible to wear after relatively short operating periods.
Such blade wear may manifest itself in inconsistent elastic cutting.
Further, it may be relatively expensive to repair worn cutting devices.

Embodiment Construction

[0040]The following term explanations may be useful in understanding the present disclosure:

[0041]“Absorbent article” is used herein to refer to consumer products whose primary function is to absorb and retain soils and wastes. “Diaper” is used herein to refer to an absorbent article generally worn by infants and incontinent persons about the lower torso. The term “disposable” is used herein to describe absorbent articles which generally are not intended to be laundered or otherwise restored or reused as an absorbent article (e.g., they are intended to be discarded after a single use and may also be configured to be recycled, composted or otherwise disposed of in an environmentally compatible manner).

[0042]An “elastic,”“elastomer” or “elastomeric” refers to materials exhibiting elastic properties, which include any material that upon application of a force to its relaxed, initial length can stretch or elongate to an elongated length more than 10% greater than its initial length and ...

Abstract

The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, methods and apparatuses for severing elastic in an advancing elastic laminate. A continuous elastic laminate may be formed by bonding elastic strands between a first continuous substrate layer and a second continuous substrate layer. As discussed in more detail below, the continuous elastic laminate may advance through a cutting apparatus that intermittently deactivates or severs the elastic strands of the elastic laminate along the machine direction.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to apparatuses and methods for manufacturing absorbent articles, and more particularly, methods and apparatuses for deactivating elastic in an advancing laminate.BACKGROUND OF THE INVENTION[0002]Along an assembly line, various types of articles, such as for example, diapers and other absorbent articles, may be assembled by adding components to and otherwise modifying an advancing, continuous web of material. For example, in some processes, advancing webs of material are combined with other advancing webs of material. In other examples, individual components created from advancing webs of material are combined with advancing webs of material, which in turn, are then combined with other advancing webs of material. Webs of material and component parts used to manufacture diapers may include: backsheets, topsheet, absorbent cores, front and / or back ears, fastener components, and various types of elastic webs and components such ...
